The Bartlett Park District has a lightning prediction system that consists of sensors measuring electrostatic charges at ground level and in the atmosphere. These electrostatic charges are invisible to the naked eye and build prior to lightning occurrences. When conditions indicate that a lightning occurrence is probable, a signal is sent to alarm horns and strobe lights. A Warning Signal (one long 15 second horn blast) will sound and strobe lights will activate when a potentially dangerous weather situation is approaching. Apple Orchard Golf Course, Bartlett Aquatic Center and Glen A. Koehler Fields all have alarm horns and strobe lights. If the strobe lights are activated, a potentially dangerous weather situation exists. Apple Orchard Community Park and Apple Orchard West Park are also included in the system's range. The strobe lights are mounted on the top of the Bartlett Aquatic Center Maintenance Building, the Apple Orchard Golf Course Clubhouse and on top of the Koehler Fields Concession Building. The system is operational during park hours from late March to mid-November.
